Abstract
A system and a method for a nanostructured film including a first layer for reflecting at least a portion of an electromagnetic radiation and a second layer for receiving the remainder of the electromagnetic radiation through the first layer and subsequently reflecting at least a portion of the received electromagnetic radiation through the first layer, wherein two electromagnetic radiations with the same wavelength reflected by the first and second layers respectively are combined to form a strengthened electromagnetic radiation, the wavelength of the strengthened electromagnetic radiation being variable based on the physical property of the first layer.
